EV mode keeps dropping out on MG HS PHEV

[Tux182]

Hey guys. Had one of these for a few days now.
Love it apart from....

Sometimes the car will start fine in EV mode. Then other times it will say 'EV mode not available'. Same deal when it's in motion.
No real patterns that I can see. What gives?

Is anyone else having similar issues or just me?

 

[Norhund]

Yes that happens when I am driving as well.

 

[Tux182]

Hmmm I have mixed feelings. Good to know I'm not alone
But is this 'normal behavior' or a common fault?

If AC is on and temperature is anything but Low, there Car may decide that you need heating. It drops out of EV mode in that instance with this message

 

[hermitdave]

What I have noticed if they is not sticky and I come to it with a EV mode switched to auto every morning. Happened a few times during the day too

Most mornings I Check to see what mode it is in , then if I select EV it normally stays like that all day.
I have never had an issue where it drops out back to hybrid apart from the usual known reasons , battery all used up or heater turned on. My wife says when she turned the back demister on this also turned off EV mode.

I have to turn it on every morning as it is off without fail.
A few times including a few minutes ago, it switched to auto mode. I had gone on school run in EV mode and return leg kicked the engine and thats how I realise EV mode is off.

My advice is to set the heater temp in LOW when using ACC. Just to check if your problem is solved then

The MG EHS dos not have a an electric heat pump, this means heating the interieur always needs the engine to run. Indeed like the other members describe lower the temperature setting in the car and the car wil start and stay in EV mode.

In my instance, the AC is on low - infact AC is off most of the times

Yes ok, try to lower your ambient temperature below the out site temperature or even turn off temperature completely to test.

how do you turn the temperature completely off (besides switching HVAC off completely - which I am for testing)

 

[mjhduncker]

From the main (home) screen go to temperature setting and press the on/off button

aaah turn of climate control off . Done that now. Previously it as HVAC off with fans running

 

[Tux182]

Awesome tips guys - thanks for that. I'm now seeing some success!

No change in behaviour - yesterday in the afternoon I switched off climate control as you suggested. Having charged overnight, started up in the morning and EV mode was off

 

[jem111111]

yes 1st thing in the morning it seems hit and miss so I always check to make sure its in EV mode.
Hopefully turning off climate control will stop hybrid mode turning on , when you have selected ev mode.

Fans running should have no impact on EV mode. There is something dodgy here, I am logging it every time I get into the car and hopefully will have enough data for MG soon

The initiator of this thread reports another problem. EV mode not supported, while driving. Your observation after overnight is something else which we all observe. It does not bother me very much. I just select it on again. Might it have something to do with charging overnight?

Correct!! EV mode not available happens when climate control demands power and that turns EV mode off.
What I observe has something to do with charging though not always. I will continue with my observations and see what MG make of it
